Thus when the blank is folded into box form and the parts 12, 12,1111: folded into position to forni the sides of the box, the ends of. the extensions l2, 12n of the v two opposed side parts 12, 12 when the exholding the blank in box forni.

' the box shown in Figures l to 7. each of a The extensions 12, 12l being of tbe same Width as the side parts 12` provide by their width a closure for the full depth of' the endof the box; and heilig. in the .vase of' length equalv to one-balfot' the width ofA the bottom part,11. they provide b v their added lengths an end closure equal to the' width of the box. The extensions 11:L are shorter thannthe depth ofthe box,-that is to say than theiwidth of the parts 12, 12 of .the blank-so that when folded against and attached to the extensions 12-, as described,

their upper edges 19 will be located considerably belowl the top of the box. The rivets .or eyelets 18, 18 are placed near the side and top edges of the extensions 11, which locationleaves s aces or )ockets-.19l o eninlr at the top edges 19 of the extensions 11, and extending between said rivetsj y The folding extensions 13", 13a at the ends of the two flaps 13. 1,3 are. cut away to fprovide inclined edges 20-s\o`"that'when"the flaps 13, 13 are folded down to .close the box, said extensions may be inserted into the spaces or pockets 19 at the ends of the box. as 'shown in Figs. 6 and 7, without interference from said rivets. The inclination of the edges 20 and the location of the rivets 18 are so correlated, that the edges 20 will approach the rivets closely inclosing the box. Since each pocket -space adjacent the location of the rivets is narrow and approaches the close contact of the parts forming the pocket at the rivets, the folding extensions 13 are frictionally gripped adjacent their edges 2O and are thus locked in the pockets.

The flaps 13, 13 are preferably made wide enougfh so that they -will overlap at their ends. When closed down. as described. they may be permanently secured by means of a string or, and preferably. b v means of a sealing strip 21 applied at the overlapped edges of the fiaps 13 and of the folding extensions 133'. 13u andv extended down a short spaceupon the top parts of the extensions A11"' below their upper edges 19. asclearly shown n-Fig. 1.

are more readily inserted into the pockets ,4

19*L provided at said top edges, thus greatly facilitating the closing of the box.

As will be manifest from an examination y of the` end view of the box in Fig. 7, the end extensions of the sides of the box,

namely` the extensions 12a need not be olif a length such that together, they will equal the width ot" the box as described and enf, til-ely clore the ends of the box, as in the ease of the ei'nbodiment illustrated in Figures 1 to 7. ll will be noted that thc extensions 11 and the folding extensions 13 provide a closure for substantially the entire end 'of the box. A box made in accordance with the invention and with still further economy in the use of material may be made in which .the extensions 12, 12a and likewise the other extensions 11a, 13, may all be shortened; the only limitations are that when the blank is folded into box form, the several extensions shall provide end closnres for the box, .and that the slots orpocket's to receive the folding extensions of the top closures sha-ll open at a level above the horlzont l.

median plane of the box in order to provide efficient locking engagement for vthe ends of the extensions of the top closures.

In the modification shown in Figures 8 and 9 the invention is embodied in a Wide, shallow box such for example, as the boxes used for laundry purposes and the like.

22 indicates the blank in this case, which is cnt, creased and slotted as before. to provide. a bottom part 23, sideparts 24, 24, top closure flaps 25, 25,l and the respective vend extensions of said parts-23a, 24, 24a, and 25a, 25. -26 indicates the transverse crease lines and 27 indicates the longitudinal crease lines. 28 indicates the slots which separate the endextensions and 29 indicates'the inclined edges of the folding extensions at the ends of the top closure alps.

The end extensions 24'* of t e sides 24 in this case, it will be noted, are much shorter in length than one-half the width of the that their end edges come to a plane above,

the horizontal median plane of the box, and the folding extensions 25'* of the top closure flaps aire long enough to project below said horizontal medianplane of the box. thus providing amp-le engagement of the endy parts of saidextensions in the pockets 31. Here again the inclined edges 29 on the extensions 25 and the location of the rlvets inclusi ve, with t-he exception that the top closure is provided bya single and wider tlap extension arranged at one end of the blank, instead of two narrower extensions, arranged one; at each end of the blank as in said Figs. 1 to 7Jinclusive.

In Fig. 1l. 30 indicates the blank which -is ont, creased and slotted as before to provideua bottom part 31, side parts 32,732.. top closure part 33 of a width equalling the bottom part,.at one end of the blank, and a narrow f iap extension 34 at the other end ot the blank; the bottom, side and top closure part-s have respective end extensions 3l, 32, .32, and 33, 35r indicates the transverse crease lines, and 36 indicates the longitudinalA crease lines. 37 indicates the slots which, separate the end'extensions and'38 indicates the inclined edges of the folding extensions 33a at the ends of the top closure part 33.

The end extensions 32, 32 being of the same width as theJside parts 32 and of a length equal to, one half the width of the nbottom part 31. provide an end closure equal to the width of the box.v The extensions 31 are shorter than the depth ofthe box soV into the spaces or pockets 40 at the ends of t .the box, as shownfn Fig.4 10,!without interference from the rivets 39, and said extensions are frictionally-gripped adjacent their edges 38 and are thus locked in said pockets. When the top closure has thus been folded down. its fr'ee marginal part .will overlap the narrow flap extension 34 on the other side wall part 32 which flap extension has been theretofore folded inwardlyu An adhesive strip 41 is then `applied to the adjacent parts of the free margin of the top closure and the top marginal part of the side wall part 32 adjacent its narrow Hap extension 34. The narrow flap extension 34 not only provides la support for'the free marginal lwithin wide limits.

part of the top closure, but also acts to stiften the box along this corner so that it more ably withstands the crushing strain when the packed boxes are piled, the one upon the other. l'

Fl'oln the foregoing, it will be manifest that the lengt-h ot' the extensions atthe sides vof the main blank, (which extensions form the end closures of the box) may be varied But they may all be made of the same length and no unnecessary stock is required for the blank to produce the box, nor is it necessary to cnt away parts and tlnls lose stock at the sides of the blank,

as heretofore has been necessary in tbc case of boxes of this character.

It will be observed that in, thc case of all ofthe forms embodying the inventions, the pockets provided at the ends ot the box for the reception of the end extensions of the top closure. (whether the same be made of a single part adapted to extend all the way lacross the top. or whether it be made in twolparts which meet or overlap along the middle line of the top of the box) are lorcatedloelow the top ot the box. lThis location aswill be manifest, greatlyf facilitates the insertion of the end extensions of the top closure into said pockets.

While in describing my invention I have referred to certain details of construction and arrangement of the parts of the box. it is to be understood that the invention is in no way limited thereto except as may be pointed out in the appended claims.

I claim as'my invention:

A box made fromffibre or paper board` having sides, a bottom, and a topy closure, the said parts being provided with end extensions to form the ends of the box, the end extensions of the bottom being Yfolded against the end extensions of the sides and being secured thereto by. laterally spaced securing means near the tops and lateral edges of said vbottom extensions, providing pockets located below the top of the box .and between said securing means` and tbe endy extensions of the top closure being reduced in width toward .their ends so as to be capable of insertioninto said pockets and between thepointswhere theend extensions yof the bottom. are secured to the. end extensions of the sides.
